As part of the "Ultimate Edition" bundle, I found nothing wrong with any of the DLC's. Amgarrak wasn't impressive, really, but I would've happily played another 80 hour game in the DA:O engine so it was worth it.

If I bought it on it's own for $15 or whatever it cost when it was released, I'd have felt a little ripped off though. It wasn't enough content for it's price point. Then again, very little DLC is.
